Too much bottled water may be bad for kids' teeth

Most bottled water manufacturers say their products are 100 percent "pure," "clean" or "natural," but few brands contain one ingredient that most Americans take for granted: fluoride. 

Fluoride is voluntarily added in most of our public water.  It helps reduce the risk for dental cavities.  When it comes to bottled water, the decision to add or not to add fluoride is left entirely up to individual manufacturers. Most do not.

There is a real concern when it comes to children.  In 2009, an Eastern Virginia Medical School study published in the journal Pediatric Dentistry found that nearly 70 percent of parents surveyed said that they gave their children bottled water to drink, either exclusively or alongside tap water.  Some experts say that turning away from tap water means more cavities and worse dental hygiene. 

Keep in mind, many dentists say the connection between bottled water and dental health is just a suspicion, with no scientific proof.
